I saw this old well the other day and although the metalwork is rusted and the rope looks dry as dust, clearly there’s water there….just look at that abundance of foliage.
I’ve got an old well in my garden too. It’s a long way down to the water but plants push their way out of the mouth of the well all year around.
Sometimes I think we take plants for granted. Look how they can take root and flourish in the least likely situations. They can spread their seeds far and wide, take root in pretty nutrition-deficient environments, capture carbon and oxygen from the air, soak up the sun’s rays and with a little water added can make themselves big and beautiful.
Human technologies just can’t match them.

Without water there is no life. Great picture, I love the look of that old well. Dan
